SHUTTER-OPERATOR.

SPECIFICATION forming part of Letters Patent No. 583,849, dated June 1,1897.

Application tiled October 3l, 1896. Serial No. 610,723. (No model.)

To all whom t may concer-rz,.-

Be it known that I, WILLIAM I3. EICH- HOLTZ, a citizen of the UnitedStates, residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented a new and useful Shutter Operating Device, ofwhich the following is a specification.

My invention relates to a shutter-bolt-disengaging apparatus adapted tobe applied to solid shutters, such as those employed in connection withwarehouses, storage-buildings, and the like; and the object in view isto provide means whereby a shutter may be openedl from the outside bymeans of a stream of water from a fire-hose to give access to theinterior of the building.

Further objects and advantages of this invention will appear in thefollowing` description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure l is a perspective view of an apparatusembodying my invention applied in the operative position to a shutter.Fig. 2 is an inside view of the same, showing the apparatus in itslocked position. Fig. 3 is a vertical sectional view of the same.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

The shutter l is provided with an opening 2, which is preferablyelongated horizontally, and covering the same and secured to theexterior surface of the shutter is a hood 3, enlarged or iared towardand open at its lower side to admit a stream of water applied by alire-hose and adapted to direct the same into the opening 2. Coveringthis opening at the inner side of the shutter is an upwardly-flaredshield 4, open at its upper side and designed to prevent the insertionof a wire or other device through the opening 2 to tamper with theshutter-locking mechanism. Secured to the shutter and inclosing thisshield is a guard 5, which is reduced toward its lower open side and isadapted to discharge into a bucket or receptacle 6, located contiguousto its lower side, and is preferably arranged within the mouth of thebucket or receptacle. The wall of the shield is extended downwardly andinwardly or toward the guard 5 to form a deflector 7, which combineswith the lower porshutter.

tion of the wall of the guard to direct the water introduced through thehood into the bucket or receptacle 6. This bucket or receptacle issupported by a bell-crank lever 8,

. having one arm connected to alocking device,

such as a bolt 9, suitable loose or flexible connections 10 and 11 beingemployed to connect the arms of said lever, respectively, with the boltand bucket. Under ordinary circumstances the weight of the bucket orrecepta-` cle is insufficient to affect the bolt, said bucket being heldelevated, as indicated in Fig. 2; but when it is desired to open ashutter from the outside a stream of water from the rehose is directedagainst the outer face of the shutter under the hood and is conducted bythe shield 4t and guard 5 into the bucket or receptacle until sufficientweight has been accumulated to draw the bolt and release the In order toopen the shutter after its release, I employ a deflecting-plate 12,secured to the exterior surface of the shutter and depressed at an angleof approximately thirty degrees thereto, and the force of water thrownby a lire-hose against the inclined surface of this plate is sufficientto swing the shutter to its open position.

From the above description it will be seen that the apparatus is simpleand, While facilitating the opening of a shutter from the outside, isadapted to prevent tampering with the locking device by the meansordinarily employed for that purpose.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacricing any of the advantages of this invention. y

Having described my invention, what I claim isl. The combination with ashutter having an opening, of an exterior downwardly-dared hood coveringsaid opening and adapted to receive a stream of Water discharged by alire-hose to guide the same into the opening, a guard covering saidopening at the inner side of the shutter and having an open lower end,an upwardly-dared shield Within the guard to throw entering wateragainst the inner wall of the latter, a shutter-locking device, and abucket or receptacle disposed beneath the open end of the guard andoperai IOO tively connected with the shutter-lookin g device Whereby thedepression of the bucket disengages the locking device, substantially asspecified.

2. The combination With a shutter having an opening, and a lockingdevice, of a downwardly-contracted guard communicating with the saidopening and open at its lower end, a bucket or receptacle operativelyconnected with the locking device and disposed beneath the open lowerend of the guard, and a down- Wardly and inwardly inclined delector 7arranged beloW the opening in the shutter and Within the guard toprevent Water from flowing between the outer side of the receptacle andthe shutter, substantially as specified.

The combination With a shutter and a WVILLIAM B. EICIlllOLTZ.
